Description
TECHNICAL FIELD
[0001] The present invention is related to a tube light, and more
particularly to a tube light structure in which an inductive
operation is changed to an electrical operation and the tube light
structure can be applied to the conventional tube light
fittings.
BACKGROUND
[0002] A fluorescence tube lamp with two contact pins on both end
portions thereof is one of the lighting devices which are widely
used around the world. The fluorescence tube lamps are mostly used
in the places where illuminance is highly required, such as
offices, factories, and hospitals. In the past decade, experimental
evidences have been proven that the impedance coils used in the
fluorescence tube lamps to constrain gas-discharging is not an
optimum lighting solution; however, since the manufacturing cost is
low and the structure is simple, the countless fluorescence tube
lamps are continuously been used.
[0003] The drawbacks of the fluorescence tube light lie in that:
when the fluorescence tube light works at the frequency 50 Hz or 60
Hz, the light emitting from the fluorescence tube lamp is
flickering and has a stroboscopic effect, which similar to a
working machine temporarily stopped. In addition, the efficiency of
inductive fluorescent lamp ballasts can't be satisfied because the
physic conversion efficiency from a discharge of invisible gas to a
visible light can be obviously increased by a nowadays electronic
device working in high-frequency through current electronic
technology; therefore, for the same lighting efficiency, the
process of discharge by using the nowadays electronic device can
save a lot of energy. It not only considers costs, but also concern
natural resources and environment protections.
[0004] Certainly, it not involves the fluorescent lamp ballast cost
only for converting the inductive type light fixture to an
electronic type light fixture by using a device working in
high-frequency. In technical and economical aspects, this kind of
conversion is feasible; however, the related works, such as
installation, are quite expensive so that it reduces the conversion
in progress. It mainly caused by tremendous conversion costs
considered by enterprisers or users and environment problems caused
by a huge amount of metal frames and ballast after conversions.
[0005] As for the above-mentioned problems, a one-piece-formed T85
tube-in-tube energy-saving fluorescence tube lamp is commonly used
in markets. It can be directly used in conventional tube light
fittings, and comprises at least an energy saving tube lamp with a
smaller diameter, an outer tube lamp for enclosing the energy
saving tube lamp, and two converters respectively disposed on two
end portions of the outer tube lamp. The terminals of the
converters are identical to the pins of the conventional
fluorescent tube lamp on two end portions thereof. In addition,
inside the one or both of the converters is disposed with an
electronic ballast consisted of a rectifier and a high-frequency
inverter.
[0006] Alternately, another kind of energy saving fluorescent tube
lamp has a length as the length of the conventional fluorescent
tube lamp and is made by an electronic driving device. Inside the
energy saving fluorescent tube lamp is disposed with the
above-mentioned electronic ballast, and two outer ends of the
energy saving fluorescent tube lamp respectively have outer pins.
The specification of the outer pins of the energy saving
fluorescent tube lamp is in compliance with the specification of
the pins on two ends of the conventional fluorescent tube light.
Then, an energy saving tube lamp with a smaller diameter is
installed in two ends of the electronic driving device.
[0007] From above descriptions, in the conventional energy saving
tube lamps, the electronic ballast consisted of the rectifier and
the high-frequency inverter has to be installed in a small space,
so that it will have a difficulty in heat dissipating, which may
damage the electronic device. Besides, the tube lamp may not be
able to provide maximum lighting due to its compact structure.
Moreover, the tube lamp may be damaged due to poor heat
dissipating. Therefore, the costs are not reduced but increased due
to such drawbacks, and a high failure rate may also bring an
inconvenience in use.
SUMMARY
[0008] One objective of the present invention is to provide a tube
light structure with a simple structure and can be made with low
cost. The tube light structure can be used to replace the
conventional fluorescent tube lamp with an economical way and
minimum or without extra work, so as to convert the operation of
conventional light fixtures into an electronic operation in high
frequency.
[0009] A tube light structure of the present invention is applied
to a fluorescence lamp lighting devices, comprising: a tube
electrical starter, comprising an outer tube, and an electrical
starting control board, wherein the electrical starting control
board is enclosed in an inner space of the outer tube, and two end
portions of the outer tube are respectively disposed with two
contact pins for inputting an electrical source to the electrical
starting control board; and at least one tube lamp, wherein two end
portions thereof are respectively disposed with a fixing part, two
fixing pins are respectively disposed on outer part of the fixing
part, one of the fixing parts is formed with an input terminal, and
the tube electrical starter is inputted the electrical source by a
wire passing through the input terminal.
[0010] In one embodiment, the outer tube of the tube electrical
starter has at least one wire for outputting the electrical source
to the tube lamp, or the outer tube of the tube electrical starter
is formed with at least one output terminal, and the electrical
source is outputted by the wire inserted into the output
terminal.
[0011] In one embodiment, the surface of the outer tube is formed
with a plurality of heat-dissipating holes.
[0012] In one embodiment, the tube electrical starter is further
disposed with a set of battery.
[0013] In one embodiment, the tube lamp and the fixing part are
detachable.
[0014] In one embodiment, the tube lamp is a fluorescence lamp, an
energy saving tube lamp having three primary colors and a smaller
diameter, cold-cathode fluorescent lamp (CCFL), or a light emitting
diode (LED).
[0015] The advantages of the present invention lie in that: a
proper length of the tube electrical starter according to the
present invention can be designed due to a world standard for the
length of fluorescence tube lamps, thereby, the tube electrical
starter having the electrical starting control board can easily be
inserted into a conventional tube light fitting or a light fitting,
and more control electrical elements can be further disposed on the
electrical starting control board. Accordingly, the
heat-dissipating effect is increased by enlarging the inner space
used for accommodating electrical devices, so that the electrical
elements are not easily damaged due to poor heat-dissipating.
Moreover, the electrical elements are detached from the tube lamp;
therefore, the tube lamp can have a maximum lighting efficiency and
wouldn't easily be damaged so as to save user's cost.

120 is a known technology, so that it will not be described
here.
[0029] Please refer to FIG. 4, it is a perspective view
illustrating a tube lamp according to an embodiment of the present
invention. The tube lamp 300 according to the present invention has
fixing parts 310, 320 on both end portions thereof, and each fixing
part 310 (or 320) is disposed with two contact pins 311, 321. One
of the fixing parts 310, 320 is formed with an input terminal 330.
A wire 200 ran from the tube electrical starter 100 is inserted
into the input terminal 330 for supplying an electrical source. The
outer tube 110 of the tube electrical starter 100 has at least one
wire 200 for supplying an electric source to the tube lamp 300. In
